Combination skin is simply having oily skin in some areas of your face and dry skin in other areas. Typically, there's a mix of oily and dry areas on different parts of your face, with the t-zone (forehead, nose, and chin) being slightly to very oily.
First decided which area is effected the most, oily or dry section. This will determine which ingredients  and products you want to choose. 
Cleanse with white boxed complexion bar and then double cleanse with rice cleansing powder. You can use one in the morning and one in the evening or depending on the level of oils produced, you can double cleanse daily. 
Deep pore clean with clear skin  toner after cleansing. 
Add some moisture and nourishment with gold elixir which also helps to trick the oi glands into thinking there is enough oil on the skin, so not to produce more.
